[0030] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] In one embodiment, Figure 1 and Figure 2 As shown, a server status monitoring method based on CPLD is provided, the method comprising:

[0032] Step S1: Receive a control instruction sent by the host computer platform, parse the control instruction, select a data signal type that is compatible with the communication method between the CPLD and the host computer platform, and record it as the selected type; and simultaneously obtain a server status monitoring data signal corresponding to the selected type according to the control instruction.

[0033] In step S1, the present application sets the communication mode between the CPLD and the host computer platform to be UART. Therefore, the CPLD has a UART sending module and a UART receiving module. The UART receiving module receives the control instructions of the host computer platform.

[0034] At the same time, the CPLD also has an instruction parsing module for parsing control commands and selecting UART type data.

[0035] Step S2: performing data framing and cross-clock domain processing on the server status monitoring data signal of the selected type to obtain a data packet.

[0036] In step S2, the data of the selected UART type is framed, and then cross-clock domain processing is performed through FIFO to achieve matching with the UART baud rate, and the corresponding data packet is sent to the host computer platform through the UART sending module.

[0037] Step S3: Send the data packet to the host computer platform, so that the host computer platform parses the data packet, locates the server status monitoring data, and performs abnormal value judgment on the server status monitoring data.

[0038] In step S3, the host computer parses the sent data packet, locates the server status monitoring data, compares the received signal with the preset correct value, and records the status of the abnormal signal and the time of occurrence.

[0039] In this embodiment, when the server is turned on, the CPLD will start the corresponding work. In order to know the status and changes of the corresponding signals inside the CPLD, the main design structure of the CPLD status monitoring system is shown in the figure above. The CPLD and the host computer display and control platform transmit and control data through UART. The host computer platform sends a control command to the CPLD to obtain the required signal data; the CPLD performs corresponding instruction parsing according to the control command, selects the corresponding signal for data framing, and then performs cross-clock domain processing through FIFO to achieve matching with the UART baud rate, and sends the corresponding data packet to the host computer platform through UART, which is displayed on the host computer platform and monitored and analyzed. The specific implementation steps are as follows:

[0040] (1) Due to the limited data transmission speed of UART, the internal signal status of CPLD is grouped according to the signal interface type and signal function, such as IIC data, UART data, I / O signal, etc.

[0041] (2) CPLD data processing and control. This is mainly divided into three submodules: instruction parsing, data framing, and FIFO modules. The instruction parsing module selects the signal to be sent according to the control command, controls the signal framing method, and controls the FIFO. The data framing module frames the signal according to the characteristics of the signal to be transmitted, so that the host computer platform can distinguish different types of data. The FIFO module performs data caching and cross-clock domain processing to prevent data loss.

[0042] (3) CPLD UART module. It is mainly used to receive commands from the host computer platform and send data packets.

[0043] (4) Host computer platform. The main functions include parameter and preset state value input, control command input, visual interface design, UART command sending and data receiving, data analysis and display, and signal abnormality status recording.

[0044] In the aforementioned CPLD-based server status monitoring method, communication is established between a host computer and the CPLD, allowing the host computer platform to send control instructions to the CPLD. The CPLD parses the control instructions and selects a data type in the CPLD that matches the communication method between the CPLD and the host computer platform. Simultaneously, a server status monitoring data signal corresponding to the selected type is obtained based on the control instructions. The selected server status monitoring data signal is framed and processed across clock domains to obtain a data packet. The data packet is then sent to the host computer platform, which parses the data packet and determines abnormal values ​​in the server status monitoring data. This allows for rapid location of server status monitoring data and timely detection of anomalies in the server monitoring data.

[0045] In one embodiment, the cross-clock domain processing includes:

[0046] The read and write clocks of the FIFO are controlled and adjusted to match the selected data signal rate and the baud rate of the communication mode between the CPLD and the host computer platform.

[0047] In one embodiment, before receiving the control instruction sent by the host computer platform, the method further includes:

[0048] The data transmission mode parameters between the CPLD and the host computer platform and the server card board CPLD signal information are sent to the host computer platform so that the host computer platform can be configured.

[0049] In one embodiment, if no new control instruction is received or no stop monitoring instruction is received, and the data signal of the selected type is updated in the CPLD, steps S2 to S3 are repeated for the updated data signal of the selected type.

[0050] In one embodiment, if a new control instruction is received, steps S1 to S3 are repeated.

[0051] In one embodiment, performing data framing on the selected type of data signal includes: adding a frame header, a frame trailer, and an identifier to the selected type of data signal.

[0052] Specifically, if Figure 3 ,The server status monitoring method based on CPLD is implemented as follows:

[0053] Step 1: The server is powered on, the CPLD starts working, and the signal monitoring system module waits to receive instructions from the host computer platform; the host computer software starts and connects to the CPLD through the UART driver circuit;

[0054] Step 2: Configure the host computer platform related parameters, including UART parameter information and corresponding server board CPLD signal information, and turn on UART;

[0055] Step 3: Enter the corresponding command into the host computer's sending command box, click Send, and send the command through the host computer's UART sending function;

[0056] Step 4: The UART receiving module of the CPLD receives the instruction and parses the instruction information, controls the corresponding signal to be framed, adds the frame header, frame footer and identifier, and controls and adjusts the read and write clock of the FIFO to match the signal rate and the baud rate of the UART;

[0057] Step 5: The UART sending module of CPLD sends the data packet;

[0058] Step 6: After receiving the data sent by the CPLD, the host computer platform parses the data packet, displays the signal in a graphical form, compares the received signal with the preset correct value, and records the status of the abnormal signal and the time of occurrence.

[0059] If there is no new instruction or monitoring is stopped, steps 5 and 6 will be repeated; if a new instruction is sent, steps 3 to 6 will be repeated.

[0060] In one embodiment, a CPLD-based server status monitoring system includes:

[0061] Data signal type selection module: used to receive control instructions sent by the host computer platform, parse the control instructions, select the data signal type that is compatible with the communication method between the CPLD and the host computer platform, and record it as the selected type; at the same time, obtain the server status monitoring data signal corresponding to the selected type according to the control instructions;

[0062] Data processing module: used for performing data framing and cross-clock domain processing on the selected type of server status monitoring data signal to obtain a data packet;

[0063] Data sending module: used to send the data packet to the host computer platform so that the host computer platform can parse the data packet, locate the server status monitoring data, and judge the abnormal value of the server status monitoring data.

[0064] The core point of this application is to add a signal monitoring system module inside the CPLD and develop a host computer display and control platform to form a CPLD-based server status monitoring system. This system allows users to obtain internal signals of the CPLD at any time and continuously and monitor and analyze them, making it easy to locate problems.
